Unfortunately the guy lives an hr away so I havent been able to see the truck myself and her has no mechanical ability. Said he had a crankshaft sensor code. Mechanic charged him $400 to replace something that had been melted. Still the problem wasn't solved so he took it to a dealer that wanted to replace the part again but with an oem one and they stated something about low compression in a valve area, again him trying to explain it to me is like pulling teeth because he has no idea what the dealer told him. Again it drives fine above 25 mph and like shit below.
